SPECIFICATION forming part of Letters Patent No. 629,483, dated July 25,1899. Application filed January 24,1899. $erial No. 703,275. (No model.)

certain new and useful Improvements in Brakes, of which the following isafull, clear, and exact specification.

This invention consists of an improved,

brake-treadle for road-vehicles. v

In carrying out my invention I provide a bracket or support whichcarries a toothed quadrant which operates a rack which is connected tothe brake-block by any suitable and well-known means, such as a rod orchain. This quadrant is connected to one end of a bent pivoted lever bymeans of a link, the other end of this lever being adapted to receivethe foot-pressure of the'operator. A spring is provided for bringing thebrake back to its inoperative position after use.

Referring to the annexed drawings, Figure 1 is a side elevation of myinvention; Fig. 2, a plan View of same.

a is a base-plate or support which carries the bearing-supports b and c,and upon which base-plate or.support a the rod d, having the rack (2upon same, slides.

f is a pinion-wheel pivoted at g, which gears in the teeth of the rack eand also with the toothed quadrant piece h, which is pivoted at 'i, andhaving the prolongation j, to which the link 70 is pivotally attached.-This link 70 is again pivotally attached to the lever Z, pivoted at m tothe support 0.

n is a surface for receiving the pressure of the foot upon the lever 0,which is pivoted at 19 to the support 0 and also at q to the lever Z.

r is a spring connected at s to the lever Z and at g to the support 6 orother suitable 'position for the purpose of bringing the mechanism toits initial or inoperative position after having been used.

It will be seen that when the end a of the lever 0 is moved in thedirection of the arrow 1 the racked rod d will be moved in the directionof the arrow 2, and to this rod are attached the connections to thebrake-block, which may be of any convenient and wellknownarrangement,-and the movement of the racked rod d in the direction ofthe arrow 2 causes the brake-block to be brought into contact with thewheel of the vehicle, which may be of any suitable class.

The mechanism is attached to anysuitable part of the vehicle through themedium of the base-plate a or support by means of screws, bolts, or thelike.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-- In brakes for vehicles of the class hereindescribed in combination; a base-plate carryinga sliding racked rod orbar in connection with the. brake-blocks, a racked quadrantpiece; asupport carried upon the base-plate, and pivotally carrying said rackedquadrant, a lever or prolongation upon said racked quadrant, a pinionwhich connects the movement of the racked quadrant, and racked bar; afoot-lever pivotally carried upon said base-plate links or leverspivotally connected to said foot-lever, and the prolongation upon
